Placing different prices per night according to the number of visitors
My question is related to the number of visitors per night. My accommodation can accommodate up to 5 guests. The cost to wash 5 sheets, 3 duvet covers, 5 or more pillowcases and 10 towels is much higher than what is needed to freshen the towels and bed linen that a single guest will need. Is there a way to place prices per night according to the number of visitors?
